sed command with variable
Hi,

I want to insert some text in the begning of each line. But issue is the text that i want to insert is stored into one variable. so my command look like
Code:
constr="`date | awk '{print $3"-"$2"-"$6}'`",MXGBTST1" "
sed 's/^/\$constr/g' alert_temp.cs

v

but sed command instead of taking constr value inserting $constr in the begning of each line.

Please tell me where i am wrong.

Thanks in Advance

vi

VI(1)							      General Commands Manual							     VI(1)

NAME

       vi - screen oriented (visual) display editor based on ex

SYNOPSIS

       vi [ -t tag ] [ -r ] [ +command ] [ -l ] [ -wn ] name ...

DESCRIPTION

       Vi (visual) is a display oriented text editor based on ex(1).  Ex and vi run the same code; it is possible to get to the command mode of ex
       from within vi and vice-versa.

       The Vi Quick Reference card and the Introduction to Display Editing with Vi provide full details on using vi.

FILES

       See ex(1).

SEE ALSO

       ex (1), edit (1), ``Vi Quick Reference'' card, ``An Introduction to Display Editing with Vi''.

AUTHOR

       William Joy
       Mark Horton added macros to visual mode and is maintaining version 3

BUGS

       Software tabs using ^T work only immediately after the autoindent.

       Left and right shifts on intelligent terminals don't make use of insert and delete character operations in the terminal.

       The wrapmargin option can be fooled since it looks at output columns when blanks are typed.  If a long word passes through the  margin  and
       onto the next line without a break, then the line won't be broken.

       Insert/delete  within  a  line  can  be slow if tabs are present on intelligent terminals, since the terminals need help in doing this cor-
       rectly.

       Saving text on deletes in the named buffers is somewhat inefficient.

       The source command does not work when executed as :source; there is no way to use the :append, :change, and :insert commands, since  it	is
       not possible to give more than one line of input to a : escape.	To use these on a :global you must Q to ex command mode, execute them, and
       then reenter the screen editor with vi or open.
